Radially Acting Operator Patents (Class 192/48.615)
  • Patent number: 8381889
    Abstract: A dual clutch, which has a first friction clutch pulled by a first lever actuator and a second friction clutch pushed by a second lever actuator. The lever actuators each have a lever that is spring-loaded on one side and lever tips which are moved by a bearing block. The bearing block can be moved radially with along a profile of the lever to set a variable contact point of the lever between a rigid base plate and the lever to act on actuating bearings of the friction clutches. The bearing block is actuated by force application in one of the radial directions of motion by a drive controlled by a control unit in an automated manner. The drive of both lever actuators is formed by a pneumatic controller. In each drive a piston is movable in a housing and is connected to the bearing block by a piston rod.
